Why People Confuse Them
All three expressions contain used, but the auxiliary verb changes the tense.
Is used
is + past participle

This is the present simple passive.
Has been used
has + been + past participle
has been used
This is the present perfect passive.
Was used
was + past participle
was used
This is the past simple passive.
The important question is:
Are you talking about a general/current situation, a past action with a present connection or a completed past event?

“Has Been Used” vs “Was Used”
This is often the most important distinction.
Compare:
The method has been used for ten years.
This suggests that the period of use continues to the present or is relevant now.
Now:
The method was used for ten years.
This normally presents those ten years as a completed period in the past.
The building was used as a school for 50 years.
This suggests that its use as a school ended.
“Is Used” vs “Has Been Used”
Compare:
This technique is used in medicine.
This describes a general/current fact.

Both can be correct, but they focus on different aspects.
General practice
The technique is used in medicine.
History/experience

“Is Used” vs “Was Used”
Compare:
This building is used as a library.
The building currently serves as a library.
This building was used as a library.
It served as a library in the past, but that may no longer be true.
This is a very useful way to understand the difference:
is used → now
was used → then
Common Mistakes
Mistake 1: Using “was used” with an unfinished time period
❌ This method was used for ten years and is still used today.
This can sound contradictory because was used presents the period as completed.
Better:
This method has been used for ten years and is still used today. ✅
Mistake 2: Using “has been used” with a finished past time
❌ The machine has been used yesterday.
Better:
The machine was used yesterday. ✅
Present perfect normally doesn’t combine with a specific finished past time such as yesterday.
Mistake 3: Confusing “is used” with “is being used”
These are different.
The machine is used every day.
= This is a regular practice.
The machine is being used right now.
= Someone is using it at this moment.
Mistake 4: Confusing “has been used” with “has used”
Remember that has been used is passive.
The machine has been used by the technician.
The machine receives the action.
The technician has used the machine.
The technician performs the action.
Is Used vs Is Being Used
This distinction is important.
Is used
General or habitual:
This room is used for meetings.
Is being used
Happening now:
This room is being used for a meeting right now.
So:
is used = generally
is being used = currently happening
Has Been Used vs Has Been Being Used
Instead of:
The machine has been being used for three hours.
Native speakers would usually say:
The machine has been in use for three hours.
or:
The machine has been used for three hours.
The simpler construction is generally more natural.
American vs British English
There is essentially no difference between American and British English in the basic use of these three forms.
Both varieties use:
is used
has been used
was used
The main differences you may encounter concern broader preferences for the present perfect versus simple past in certain contexts, but the fundamental grammar remains the same.
Memory Trick
Think of the three forms as a timeline:
IS USED → NOW / GENERALLY
HAS BEEN USED → PAST → NOW
WAS USED → PAST → FINISHED
Example
Is used:
This tool is used every day.
Has been used:
This tool has been used every day since Monday.
Was used:
This tool was used every day last week.
One line memory trick:
Is = current/general, has been = past connected to now, was = completed past.
Final Verdict
Use is used for general, habitual or current use:
This software is used by many companies.
Use has been used for past use that connects to the present:
This software has been used by many companies for years.
Use was used for a completed past situation:
This software was used by the company last year.
Simple rule:
Is used → generally/now
Has been used → from the past up to now
Was used → finished past
